Abstract

Earlier, we developed the I-propanol probing methodology that could separately evaluate the relative hydrophobicity and hydrophilicity scale of a given sample. We applied it here to fructose, glucose, sucrose, and trehalose and evaluated the same for these saccharides. We then construct a two-dimensional map with the hydrophobicity and the hydrophilicity axes and plot the above saccharides together with other nonelectrolytes subjected earlier to the same analysis. We point out that these saccharides together with other so-called "osmolytes" that accumulate in vivo under H2O Stress occupy a small specific region near H2O in this map.
